Blind spot warning system fails on occasion to detect/warn of vehicle (most notably, semi truck and trailers) in blind spot on the right side of car when traveling on interstate highways. Also when I’m completing my passing of the said trucks, the left side blind spot monitor will activate to indicate a vehicle to my left when there is no lane for a vehicle to pass by me from the left. (Video evidence is available). The dealer has on two occasions been informed of these incidents, on 12Nov24 @15890 miles and 27May25 @22217 miles. The dealer mechanic/technician has stated that they could not duplicate this phenomenon while test driving, nor could they find any error codes or malfunctions in the system. Dealer has stated the car is operating properly and is ‘safe’ to drive. Dealer has not and refuses to escalate this problem to the Manufacturer. These incidents have occurred since new as of Nov2023 to present May2025
